A computer seized from the home of a former pediatric nurse at OHSU's Doernbecher Children's Hospital held sexually explicit images of two little boys that might have been taken at the Portland hospital, according to federal court records.

The images were among more than 400 recovered from a Toshiba laptop seized from the home of Bryan W. Corbitt, a 43-year-old Washougal, Wash., man charged last week with receiving, possessing and distributing child pornography.

Corbitt is being held at SeaTac Federal Detention Center 12 miles south of Seattle. He is scheduled to appear Thursday in a detention hearing before U.S. Magistrate Judge Karen L. Strombom, in Tacoma.

Federal investigators searched Corbitt's home on Feb. 1, interviewing him and his wife. Corbitt told them he went to work as a pediatric nurse in Doernbecher's Intensive Care Unit in March 2001, court records show. Hospital officials reported that he worked there from July 15, 2002, until Feb. 1, when he was placed on unpaid administrative leave.

The hospital accepted his resignation on Feb. 10, one day after a federal investigator went to the hospital in hopes of identifying the boys in the explicit photos. Both images focused on the genitalia of the boys, each with catheters inserted into them. A male hand holds one boy's genitals. The other boy reclines on a diaper.

"Ms. Brown stated that she recognized the catheters and the diapers in the images as being the same ones that are used at Doernbecher," Peay wrote in an affidavit to obtain a search warrant for Corbitt's locker at the hospital.

On Tuesday, OHSU spokesman Jim Newman said neither OHSU nor federal investigators know definitively whether the photos were taken at Doernbecher. Newman pointed out that the catheter was made by Bard, the diaper by Pampers -- both commonly used across the United States.

"We don't want to alarm people, but we also want families to receive information as it comes out," Newman said. "As we learn more information, we want to share that."

Corbitt's troubles began last November, when an undercover federal agent posing as a collector of child pornography made his acquaintance online. Corbitt, using the screen name "Kidluver," is accused of passing dozens of illegal images to the agent.

When agents searched his home on Feb. 1, they interviewed his wife, Krista Corbitt. She told them that in 2006 or 2007, she had found images of naked boys on the family's desktop computer, according to Peay's affidavit.

"Mrs. Corbitt stated that the boys in the images were approximately eight years old. Mrs. Corbitt said that her husband initially blamed their oldest son, but eventually admitted to downloading the images, which were located in a hidden file," according to the affidavit.

Federal agents later searched Corbitt's locker at the hospital, but found nothing of value in their investigation.
